LOS ANGELES—Mindy McCready has threatened legal action against Vivid Entertainment Group if it doesn't destroy the sex tape of her with her ex-boyfriend that the company is set to release.

According to TMZ.com, the lawyer for the country singer and reality TV star sent Vivid a cease and desist letter that claims the tape was "never intended for sale or public distribution."

Vivid's tape, titled Mindy McCready, Baseball Mistress, is said to include footage of the singer talking about her sexual exploits with former Major League pitcher Roger Clemens, among other high profile celebrities.

According to the report, the lawyer believes Vivid does not have the right to distribute the tape that McReady claims was stolen from her home three years ago.

Vivid executives were unavailable for comment at press time.
